The game was heavily promoted and released to near-universal acclaim during Xbox LIVE Arcade's first "Summer of Arcade" event.

Claire is captured by black ops troopers, and Jason pursues her and her captors into an underground base, where a sinister organization called the Restoration is waiting to bring forth what it believes will be a new golden age for America and the world. You think this would be a fun little date, right? A woman named Claire and the man interested in her, Jason, go on a date that involves spelunking.
